Previously when copying the allocator state we would copy an incorrect root pointer into the document's current state; while this had a minimal impact on the allocation state due to the fact that any new allocation would need to create a new page, this used a potentially stale field of the moved document when setting up new pages, which could create issues in future uses of the pages. This change fixes the core problem and also removes the use of the _root->allocator from allocate_page since it's not clear why we need it there in the first place.
pugixml 
pugixml is a C++ XML processing library, which consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving).
pugixml is used by a lot of projects, both open-source and proprietary, for performance and easy-to-use interface.
Documentation
Documentation for the current release of pugixml is available on-line as two separate documents:
- Quick-start guide, that aims to provide enough information to start using the library;
- Complete reference manual, that describes all features of the library in detail.
You’re advised to start with the quick-start guide; however, many important library features are either not described in it at all or only mentioned briefly; if you require more information you should read the complete manual.
Example
Here's an example of how code using pugixml looks; it opens an XML file, goes over all Tool nodes and prints tools that have a Timeout attribute greater than 0:
#include "pugixml.hpp"
#include <iostream>
int main()
{
pugi::xml_document doc;
pugi::xml_parse_result result = doc.load_file("xgconsole.xml");
if (!result)
return -1;
for (pugi::xml_node tool: doc.child("Profile").child("Tools").children("Tool"))
{
int timeout = tool.attribute("Timeout").as_int();
if (timeout > 0)
std::cout << "Tool " << tool.attribute("Filename").value() << " has timeout " << timeout << "\n";
}
}
And the same example using XPath:
#include "pugixml.hpp"
#include <iostream>
int main()
{
pugi::xml_document doc;
pugi::xml_parse_result result = doc.load_file("xgconsole.xml");
if (!result)
return -1;
pugi::xpath_node_set tools_with_timeout = doc.select_nodes("/Profile/Tools/Tool[@Timeout > 0]");
for (pugi::xpath_node node: tools_with_timeout)
{
pugi::xml_node tool = node.node();
std::cout << "Tool " << tool.attribute("Filename").value() <<
" has timeout " << tool.attribute("Timeout").as_int() << "\n";
}
}
